The increasing demand for cleaner fuels and the recent stringent regulations of commercial fuel specifications have driven the\nresearch of alternative methods to upgrade the current industrial desulfurization technology. Adsorptive desulfurization, the\nremoval of refractory sulfur compounds using appropriate selective tailor-made adsorbents, has shown up as a promising alternative\nin the recent years. Carbon nanomaterials, namely, graphene, graphene oxide, carbon nanotubes and carbon nanofibers,\nshow a significant potential as desulfurization adsorbents. Their surface area and porosity, their ability of easy functionalization,\nand their suitability to serve as a support of different types of adsorbents have rendered them attractive candidates for this purpose.\nIn this review, after a presentation of the current industrial desulfurization practice and its limitations, the structure and properties\nof the carbon nanomaterials of interest will be described, followed by a detailed account of their applications in adsorptive\ndesulfurization. The major literature findings and conclusions will be presented and discussed as a road map for future research in\nthe field.
